Where is the observatory ?

The site of the observatory was selected by making a compromise between several parameters arranged in decreasing order of importance.

  1. The objective of this project is to take advantage of the remote control to throw off problems of physical accessibility and to exploit "a good astronomical site". A summit of mountain was essential.
  2. Our means do not enable us to consider a setting up outside of Metropolitan France.
  3. Construction must be authorized (by the administration). What is not obvious with the present law.
  4. The clouds must be rare. ensoleillement
  5. The local geography must not be at the origin of atmospheric turbulences.
  6. In general terms, the site must allow the observation of the sky under the best conditions (weak luminous pollution, open horizon, etc...).

The small white round indicates the site of the observatory.

Visibility ideal site

To find a cloudless mountain sky, we chose the South Alps. The first west summits of the range, in the Haute Provence Alps profit from the cloudless sky of the south of the Rhone valley.

To avoid the atmospheric turbulences generated by the neighbouring mountains, we limited ourselves to lonely summits.
